Pulse tail suppression in laser diode output by tunable notch filter

Dubov, Mykhaylo, Giannone, D., Khrushchev, Igor and Bennion, Ian (2001). Pulse tail suppression in laser diode output by tunable notch filter. Electronics letters, 37 (23), pp. 1404-1405.


Efficient suppression of relaxation oscillations in the output signal from an overdriven gain-switched laser diode was demonstrated. Several quantum-well distributed feedback laser diodes from different manufacturers were used for experimental analysis. A five-fold increase in the peak power was achieved for the tail-free operation. It was found that spectral filtering removed the nonlinearly chirped components resulting in pulse shortening by a factor of three.
